American Dynamism Film Series Spotlights Startups in Defense, Nuclear Power, and Minerals
The American Dynamism Film Series highlights three companies targeting foundational infrastructure: Ulysses in maritime technology, Radiant in portable nuclear power, and Mariana Minerals in autonomous extraction and refining.
Will O’Brien of Ulysses asserts future conflicts will center on oceans, requiring government defense entities to serve as anchor customers that accelerate deep tech development much like the Cold War space race.
Doug Bernauer of Radiant outlines plans to mass-produce trailer-mounted megawatt nuclear reactors at a rate of one per week from an 80-acre Tennessee facility for off-grid deployment within 48 hours.
Turner Caldwell of Mariana Minerals details using reinforcement learning to automate decisions across mining and refining, aiming to overcome labor bottlenecks and legacy manual tracking methods.
Maritime Tech and Defense as an Anchor Customer
Will O’Brien of Ulysses frames the current era as defined by maritime conflict rather than land warfare, predicting that future defense engagements will occur over oceans. Drawing comparisons to the Cold War space race, O'Brien notes that massive early investment pulled technological timelines forward by decades, laying the foundation for modern commercial aerospace. He positions defense departments as critical anchor customers capable of funding early-stage research and development to advance maritime technologies up the readiness scale.
Assembly-Line Nuclear Reactors for Off-Grid Power
Doug Bernauer of Radiant contrasts traditional nuclear mega-projects—which take five to fifteen years to dig and build—with factory-manufactured nuclear products. Radiant is targeting the production of one megawatt-scale reactor per week from a recently acquired 80-acre facility in Tennessee. Built as mobile units on trailers, these reactors are designed to be driven or flown to off-grid locations and activated within 48 hours, treating electricity generation as an essential, plug-and-play utility.
Autonomous Systems Across Mining and Refining
Turner Caldwell of Mariana Minerals emphasizes unifying the entire supply chain from extraction through refining to eliminate operational inefficiencies. Because geological feedstocks vary continuously, the company applies reinforcement learning to automate adjustments in flow rates, temperatures, residence times, and chemical additions without requiring human intervention. Caldwell notes that mineral operations face severe labor constraints and often rely on pen, paper, and ad-hoc spreadsheets, which software and automation seek to modernize.

*Today we’re pleased to share the American Dynamism Film Series: a spotlight on three companies changing how we build, power and defend America.*
“We have some periods in time that are defined by land, and this century we’re moving into a century that is defined by the sea. The last wars were fought in jungles and deserts. The next wars will be fought over oceans. And I think this is going to position DoW as one of these anchor customers for companies like the three of ours, to fund early-stage R&D, to get these technologies pulled up the technology readiness scale.
“With the Cold War, we had the space race, and we saw this insane investment as a percentage of GDP into the space race. It literally pulled forward the technology timelines 50 years. We did in less than 10 years what people thought we’d do by the turn of the century. ... When you have that pull forward of technology, then therefore you get that you had to have NASA to have SpaceX, right? ... And I think this is important, because government is typically an anchor customer to pull forwards in these deep technologies. I think we’re seeing a transition in this century.” — [Will O’Brien, Ulysses](https://www.blackflag.vc/episode/the-ocean-is-the-new-space?utm_source=chatgpt.com#transcript)
“Nuclear reactors as products have never been seen before. They’re always usually these giant mega projects where you dig a huge hole in the ground and it takes five to 10 years, or up to 15 for the slower, bad projects out there. Ours, we’re targeting one per week coming off of a production line from our Tennessee facility, an 80-acre site we just signed for in October, not even a year ago.
Our product is for off the grid — megawatt reactor on a trailer. We build it in our factory, we drive it or fly it to where the customer wants it to go, and then turn it on within 48 hours. ... Electric power is civilization. If you go and there are sockets, and you pop something into them and you just get power, that’s very well developed — that’s civilization, using electricity to do what you could otherwise only do with human muscle or animal muscle.” —[Doug Bernauer, Radiant](https://m.youtube.com/watch?v=1n5xlfRLw3c&ra=m)

“We focus on the full chain from mining all the way through refining. ... That handoff in the middle leads to a lot of actual market inefficiencies. We’re making a big bet on autonomy, fundamentally. ... We use reinforcement learning to actually remove humans from the loop in determining how refineries operate. When you have a highly variable feedstock — because the earth is heterogeneous — you need to constantly be tuning the temperatures, the flow rates, the chemical addition rates, the residence times of a highly complex refining circuit.
The same is true on the mining side of things — we’re making thousands of decisions a day, and when you don’t have the labor pool of folks who are able to make the right thousand decisions, that can cascade into low productivity, low availability of equipment, and low utilization of equipment.
What sets the rate of software and technology penetration into these plants and mines, ultimately, is the operating teams — what tech stack they’re comfortable with. For the most part, that’s pen and paper and maybe 150 spreadsheets scattered around an operation.” — [Turner Caldwell, Mariana Minerals](https://a16z.com/podcast/energy-minerals-and-the-physical-stack-behind-ai/)
